3 Claims.

My invention relates to building block tile for buildings or otherstructural units and has for its main object to provide fireproofbuilding block tile which may be quickly and easily secured to theframing of structure in interlocked relation, by anyone handy withtools, without employing the use of cement or mortar as a borfd, or theservices of a skilled mason or bricklayer.

A further object of the invention is to provide a building block tilewhich when secured to the framing of the structure, so encases theframing members as to make the structure, the framing and membersthereof fireproof.

A still further object of the invention is to provide a building blocktile which may have the surface which is exposed to the elements,hereinafter called the outer surface, formed decoratively or to takestucco, or other facing material, and the inner surface formed to takeplaster or plaster board.

A further object of the invention is to provide a building block tilewhich may be so fastened or connected with the framing of the structureas to practically form an integral part therewith.

These and various other objects and advantages will be readilyunderstood from the following description and accompanying drawing, butit will be noted that certain modifications may be made withoutdeparting from the scope of the invention.

In order that my invention shall be thoroughly understood I shall referto the several illustrations of the accompanying drawing in thefollowing description. In said drawing I have shown one form of theconstruction of the invention, but it is understood that I do not wishto limit myself to such form since the invention, as expressed in theclaims, may be embodied in a plurality of forms.

Fig. 1 represents a sectional plan view of walls constructed withbuilding tile of my invention,

Fig. 2 is a perspective front view of the building block tile secured tothe framing,

Fig. 3 is a top plan view of the tile,

Fig. l is a side view of the building block tile,

Fig. is an enlarged, fragmentary view of part of the building blocktile.

Figs. 4 and 5 are drawn to a larger scale than other views.

Figs. 1 and 2 show part of the frame structure of a building to which myblock tiles 11, are secured. The blocks may be made of any fireproofmaterial, preferably rectangular in shape, and of a length which equalsthe distance between two or more of the studs, joists, or rafters 10 ofa building. They have hollow ducts 12, to reduce the weight of the blockand permit the circulation of air. The ducts also act as heat and soundinsulators. Each of the block tiles have flanges 13 and 14 at each end,as well as an intermediate flange or wall 15. The duct 5 12 are locatedin rearwardly extending parts 16, which fill in the space between thejoists 10, and which are made of a depth equivalent to the or metalframing when such width of the joists is used.

The block tiles are secured to the framing by 10 fastening means such,for example, as nails 1'7. These nails are inserted in counterbored orslotted holes 18. After the block tile has been nailed in place thecounterbored recesses are suitable protective material protects the nailheads.
